I spent the morning at Flight of the Navigators place helping him drill his horizontal stabilizer to the fuselage and rivet the ILS doubler plate, but mostly it was spent chatting RV! After lunch I did a bit of everything. First I mixed up some fuel tank sealant to fill the gap in the skin where the cut out for the pitot mast wasn’t quite perfect. Then I fitted and riveted the pitot mast in place. After that I riveted the nutplates to the outboard skin access plate. I gave the wing a good clean with thinner too as it was covered in paint dust and markings.
After that I noticed that I had not primed the overlap of the aft skin. I decided I wanted it primed as it would be in contact with other parts of the aileron. So I masked off both left and right aileron skins and then sprayed them with Acid 8 etch primer as a base coat.
The Acid 8 only takes about 20 minutes before it can be overcoated so I primed the inside of the aileron counterbalance weights with PR143 while I waited. Once dry I primed the overlaps with PR143 as well.
I’ll leave the skins and weights to dry to dry for a day or two before I start assembling.
